Summary

llm.py hardcodes anthropic/claude-3.5-sonnet as the model identifier. Switching models requires a code change and redeployment.

What to do

  • Add a MODEL (or LLM_MODEL) entry to config.py that reads from the environment, defaulting to anthropic/claude-3.5-sonnet.
  • Update llm.py to use config.MODEL instead of the hardcoded string.
  • Document MODEL in .env.example.

Acceptance criteria

  • Setting MODEL=openai/gpt-4o in the environment causes the app to use that model for analysis.
  • Default behavior is unchanged when MODEL is unset.
  • No model name strings remain hardcoded in llm.py.

## Summary `llm.py` hardcodes `anthropic/claude-3.5-sonnet` as the model identifier. Switching models requires a code change and redeployment. ## What to do - Add a `MODEL` (or `LLM_MODEL`) entry to `config.py` that reads from the environment, defaulting to `anthropic/claude-3.5-sonnet`. - Update `llm.py` to use `config.MODEL` instead of the hardcoded string. - Document `MODEL` in `.env.example`. ## Acceptance criteria - [ ] Setting `MODEL=openai/gpt-4o` in the environment causes the app to use that model for analysis. - [ ] Default behavior is unchanged when `MODEL` is unset. - [ ] No model name strings remain hardcoded in `llm.py`. ## Reference ROADMAP.md — P2 Backend — Make LLM model configurable

Triage: RESOLVED

This issue has been fully implemented in the fork main branch.

Evidence:

  • config.py reads MODEL from environment, defaulting to anthropic/claude-3.5-sonnet (line 43).
  • llm.py uses config.model instead of a hardcoded string (line 28).
  • .env.example documents the MODEL variable with supported values.

All acceptance criteria are met. Recommending closure.
